God, after the first game of Ostheer I played, that's exactly what I thought.
I love the T2 start as Wehr, it's really flexible and you have your first PG by the 3rd or 4th minute
What I do is I just build 1 extra pio giving me 2 pioneers, tech ASAP and then build T2 ASAP.
Then I go for 2 PGs and one scout car and a halftrack somewhere and the rest is dependent on what he builds, but staying in T2 for a lot of the game is perfectly viable. If you decrew support weapons, I tend to take them by using my pioneers and just reinforcing with the halftrack which is why the halftrack is essential.
One major disadvantage is the lack of indirect fire. This makes it very difficult to take on mg/AT although the mortar halftrack solves that somewhat? I just get the German artillery vehicle if I really need it. You'll definitely have the fuel by there
